watchgod module not found

Hi, there:

  Following the procedure, but there is something wrong when visit the pythonanywhere website.
  In the error_log, it says:

ModuleNotFoundError: No module named 'watchgod' "

  I try to install again the watchdog module 
  "python -m pip install watchdog   ", but it doesn't help. 

  Thanks for the help.
